Took a break from babysitting but looking for extra income again! I have 9+ years of experience working with kids! I babysat as my main income thru college and was a snowboard instructor for ages 4-7! I love to hangout with kids and I can promise I won’t sit on my phone the whole time like some sitters… I love to play & follow the kids lead in what we do! Happy to answer any questions about myself!!
Hi, I’m Lydia Grace! I recently graduated from the University of Washington with a BS degree in Biology and am taking two gap years before attending medical school with a focus in maternal-child health. I am also certified in CPR/First Aid for Adults, Children, and Infants, so safety and reliability are always my absolute top priorities in the household. I have worked as a childcare provider for 4 years, gaining extensive experience across a wide range of age groups and developing the skills to confidently care for up to four children at once. I care deeply about contributing to children’s growth and well-being, and I recognize the vital importance of age-appropriate activities. I love leading kids in engaging crafts, outdoor play, and reading to support their ongoing developmental milestones. Additionally, I have a background in tutoring and am always happy to help with homework, especially in STEM subjects and Spanish. I am also completely comfortable preparing healthy meals for the kids and keeping the house tidy and organized. I look forward to bringing a blend of fun, developmental engagement, and reliable, safety-focused care to your family! Please feel free to reach out with any questions. :)

Hello families, as my contract is coming to an end soon, I am searching for a new part-time role in the mornings. Availability: 20-30 hours weekly, between 6 AM and 12 PM. A little bit about me: - I have a reliable car. - Clean driving record. - CPR certified. - Non-smoker. - Up to date with all vaccines. - Bilingual (Portuguese and English). - Very outdoorsy. I am enthusiastic, energetic, caring, and patient. I am also very punctual and love pets. North Seattle is preferable, but I’m happy to travel further for the right fit. If you’d like more information, please don’t hesitate to contact me. Thank you!

"We were incredibly grateful that Maya was able to help us out with a last-minute childcare emergency. She matched our 9-year-old's energy with arts & crafts, some quiet reading, and a walk around the neighborhood. We'd have Maya back in a heartbeat!"
